Simple Looker Embed SDK Demo (Go)

This demo showcases basic Go code for using Signed Embed to render a Looker Dashboard locally.

It utilizes Docker containers for a streamlined setup.

Prerequisites:

• Docker and Docker Compose installed (https://docs.docker.com/)

Steps:

1. Generate Looker API Credentials:

   • Access your Looker admin panel and navigate to your user settings.
   • Click "API Keys" and generate a new Client ID and Client Secret. Copy them for later use.

2. Set Up Environment Variables:

   Option 1: Using the Provided .env.sample File

   • Copy the provided .env.sample file to .env.
   • Edit the .env file and replace placeholders with your Looker credentials:
     • LOOKER_CLIENT_ID
     • LOOKER_CLIENT_SECRET
     • LOOKER_SERVER_URL

3. Run the Demo:

   • Open a terminal and navigate to the project directory.
   • Run docker-compose up --build to start the demo environment.
   • Access the demo application in your browser at http://localhost:8080/.

Deploy to Cloud Run

This option will allow you to run the project as a hosted Cloud Run app. This requires that all previous steps were completed, including the .env file configuration part with the proper credentials.

1. Source the environment variables

source .env

2. Create secres on Secrets Manager

printf "${LOOKERSDK_CLIENT_ID}" | gcloud secrets create LOOKERSDK_CLIENT_ID --data-file=-
printf "${LOOKERSDK_CLIENT_SECRET}" | gcloud secrets create LOOKERSDK_CLIENT_SECRET --data-file=-

3. Deploy the service to Cloud Run

gcloud run deploy looker-embed-demo \
   --set-env-vars="LOOKERSDK_BASE_URL=$LOOKERSDK_BASE_URL" \
   --set-secrets="LOOKERSDK_CLIENT_ID=LOOKERSDK_CLIENT_ID:latest,LOOKERSDK_CLIENT_SECRET=LOOKERSDK_CLIENT_SECRET:latest" \
   --region us-central1 \
   --source .
